Pediatric capitellum fractures are rare, accounting for <1% of elbow fractures in children. They are typically caused by axial loading on an outstretched arm. Due to the high cartilaginous composition of the pediatric elbow, these fractures are often missed in radiographic diagnosis. Proper diagnosis using computed tomography or magnetic resonance imaging is essential for effective treatment planning.
A 14-year-old female sustained a left elbow injury following a fall while playing. Clinical and radiological evaluations confirmed a displaced Hahn-Steinthal fracture of the capitellum. Open reduction and internal fixation using bio-absorbable K-wires were performed. Postoperatively, an above-elbow cast was applied for 4 weeks. At 10 weeks, the patient had achieved a full range of motion, and radiographic assessment confirmed fracture union.
Pediatric capitellum fractures, though rare, can lead to significant morbidity if not diagnosed and treated in a timely manner. The use of bio-absorbable K-wires offers an effective fixation method, eliminating the need for a second surgery for implant removal. Early intervention, proper radiological assessment, and surgical management result in excellent functional outcomes with minimal complications.
儿童肱骨小头骨折较为罕见，占儿童肘部骨折的比例不到1%。它们通常由伸直手臂时的轴向负荷引起。由于儿童肘部软骨成分含量高，这些骨折在X线诊断中常被漏诊。使用计算机断层扫描或磁共振成像进行正确诊断对于有效的治疗计划至关重要。
一名14岁女性在玩耍时摔倒后左肘部受伤。临床和影像学评估证实为肱骨小头移位性哈恩-施泰因塔尔骨折。采用生物可吸收克氏针进行切开复位内固定。术后，应用上臂石膏固定4周。10周时，患者实现了全范围活动，影像学评估证实骨折愈合。
儿童肱骨小头骨折虽罕见，但如果不及时诊断和治疗，可能导致严重的发病情况。使用生物可吸收克氏针提供了一种有效的固定方法，无需进行二次手术取出植入物。早期干预、正确的影像学评估和手术管理可带来极佳的功能结果，并发症最少。
